Children with plastic bronchitis,characterized by unknown origin,insidious onset,rapid progress,severe symptom and high mortality,is a relatively rare disease.Also,it is difficult to diagnose and treat with plastic bronchitis characterized by marked airway obstruction,via the formation of large gelatinous or rigid airway cast.It is associated with certain diseases including bronchial asthma,cystic fibrosis,accompanied with acute chest syndrome with sickle cell disease,congenital heart disease and bacterial and viral respiratory infection.Clinicians should be aware of this disease,and early bronchoscopy should be intervened.

Retinal ischemia-reperfusion injury (RIRI) is a common pathological and physiological clinical oculopathy,which can occur in retinal artery and vein occlusion,diabetic retinopathy and acute angle-closure glaucoma.The resulting ischemia can cause cell metabolic dysfunction,serious retinal damage and descending visual function.RIRI is the result of multiple factors.The currently accepted hypotheses mainly include the injury effect of oxygen-derived free radicals,intracellular calcium overload,the action of leucocyte and apoptosis.However the protection and treatment research in the RIRI is limited.The present paper reviews the progression in the drug intervention of RIRI.

Fatigue is one of the most common complaints in cancer patients that profoundly affects all aspects of quality of life.However,cancer-related fatigue remains under recognized and poorly treated.This rcview has been conducted with the causes and potential treatments of fatigue in cancer patients.The methods for evaluating fatigue,and possible therapeutic options are also discussed.

Objective To investigate the prevalence of diabetic foot (DF) and the normal,high and low ankle brachial index (ABI) in type 2 diabetic patients and explore the risk factor for abnormal ABI and the clinical predictive value for DF.Methods A total of 2681 type 2 diabetic patients who visited our hospital between January,2007 to December,2009 were enrolled in the study.The clinical data were analyzed and the risk factors for abnormal ABI were determined by logistic regression analysis.Results ABI was normal (0.9-＜ 1.3) in 2362 cases (88.1％),while below 0.9 in 277 cases (10.3％) and equal or over 1.3 in 42 cases (1.6％).The elderly patients (≥ 60 years) had a higher prevalence of low ABI than the non-elderly patients(20.41％ vs.4.10％,P ＜ 0.01).The prevalence of DF was 25.63％,3.05％,26.19％ in ABI ＜ 0.9,0.9-＜ 1.3 and ≥ 1.3 groups,respectively,and the prevalence in groups ABI ＜ 0.9 and ≥ 1.3 was higher than that in group ABI 0.9-＜ 1.3.Similar U-shape distribution was observed in the prevalence of abnormal ABI and DF.ABI was negatively correlated with age,diabetes duration,uric acid (UA),24 hours microalbuminuria,while positively correlated with body mass index (BMI),diastolic blood pressure,triacylglyceride,total cholesterol and glycosylated hemoglobin A1c (HbA1c).Abnormal ABI was independently correlated with age,diabetes duration,HbA1c,UA,24 hours microalbuminuria,diabetic kidney disease,diabetic retinopathy,diabetic peripheral neuropathy and diabetic vascular diseases.Conclusion The prevalence of abnormal ABI is higher in the elderly patients with type 2 diabetes.Abnormal ABI could be an early predictor for DF.

Objective To investigate the association between Down's syndrome(DS) and congenital heart diseases(CHD).Methods A total of 575 cases with DS from Jan.1997 to Mar.2013 in Children's Hospital of Chongqing Medical University were recruited.Retrospective study was conducted to analyze the prevalence and types of CHD in DS children,the relationship between the karyotype of DS and the types of CHD,and pulmonary hypertension (PH) and operation treatment.Results There were 370 cases(64.35％,370/575 cases) with CHD in 575 cases with DS.Among the 370 cases of CHD,322 cases (87.03 ％) were septal defects.In which,57 cases (15.41％) were atrial septal defects,36 cases (9.72％) were ventricular septal defects,12 cases (3.24％) were atrioventricular septal defects,and 157 cases(47.30％) were complex septal defects.Forty-eight cases(12.97％,48/370 cases) were nonseptal defect types of CHD (including patent ductus arteriosus,tetralogy of Fallot,double outlet right ventricle,pulmonary atresia,and so on).There was no statistical significance between the karyotype of DS and the types of CHD.There were 246 cases(66.49％,246/370 cases) with PH.Seventy cases(18.92％,70/370 cases) had interventional or surgical operations.All of them had descending pulmonary artery pressure after operation.Forty cases had other malformations such as gastrointestinal tract malformation,polydactylism / polydactyly,visual impairment,and so on.Conclusions The most common type of CHD with DS was atrial septal defect,and the second one was ventricular septal defect.There was no relationship between the karyotype of DS and the types of CHD.The patients with CHD in DS were prone to develop PH.So the comprehensive treatment plan should be developed as early as possible.

Integrative Chinese and western medicine therapy exhibited their achievements in reducing adverse reactions, improving the quality of life and prolonging the survival of the primary liver cancer (PLC) patients, which are reflected in the results of surgery, interventional therapy, chemotherapy, radiotherapy, recurrence and metastasis, promoting the liver cell apoptosis, and enhancing the effect of western medicine therapy. This article mainly overviews the current situation of clinical and experimental researches.

The studies on Internet public opinions in domestic library and information field from 2004 to 2013 were analyzed by subject analysis,which showed that studies on the hot spots of Internet public opinions using bibliometrics and knowledge map were rather mature while studies on how library and information science provides the theoretical support for Internet public opinions in its service were immature. The problems in studies on Internet public opinions in library and information field should be further studied, including their objectives, theoretical support, techniques and application.

The pathogenic basis of degenerative retinal diseases is structural and functional abnormality of neuron of retina.The irreversible damage of visual function is the unfortunate results of degenerative retinal diseases,and some effective treating approach to these blindness eye diseases is still in expectation.In recent years,stem cells replacement therapy is increasingly developed and is a prospective way for degenerative retinal diseases.But some formidable challenges for successfully grafting cells to the retina are waiting for further solving,such as migration,survival,and differentiation of the stem cells etc.Recent studies showed that retinal tissue engineering technique may be a good alternation to address all the problems mentioned above.The current advances in stem cell and tissue engineering retina researches,including selectable seed cells,appropriate scaffold materials and transferring method in vivo,are reviewed in this paper.

Objective To assess the feasibility of real-time Bi-Plane in observing normal mitral annular areas in different gestational ages.Methods Routine two-dimensional echocardiography and real-time Bi-Plane were used to observe mitral structure and measure the mitral annular area in 159 fetuses.Pearson correlation analysis was used to evaluate the correlation of the areas with gestational age.Visualization rates and acquisition time were recorded and analyzed statistically.Resuits The mitral annular areas measured by two techniques were both correlated to the gestational age (r=0.71,0.75,both P＜0.05).There were significant differences in visualization rate (x2 =4.375,P=0.036) of mitral annular area and acquisition time (t=6.11,P＜0.05) between routine two-dimensional echocardiography and real-time Bi-Plane.Conclusion Real-time Bi-Plane technique is direct,accurate,convenient and fast in observing mitral prenatally.By using Bi-Plane technique to measure mitral annular area,abnormal morphology changes of mitral valve can be evaluated,so as to provide great application value for clinic.

Objective To investigate the clinical significance of DNA haploid analysis for malignant degree and prognosis assessment of breast carcinoma. Methods Highclarity Colourful Pathological Analysis System-1000( HPIAS-1000) was used to analyze the DNA haploid of 120 breast carcinoma patients who had been followed up for more than 5 years. All patients were divided into three groups according to histology. 48 advanced differentiation cases, 44 middle differentiation cases and 28 low differentiation cases. Then DNA haploid analysis was made,that is diploid(2C) ,3 - 4C,aneuploid(AN). Results Except for 3 -4C,there were significant differences betweenⅠandⅡgrade ,ⅡandⅢgrade,ⅠandⅢgrade( P
